This is the first game in the Bubble Bobble series. For other games in the series see the Bubble Bobble category.

Bubble Bobble(バブルボブル,Baburu Boburu?) is an arcade game by Taito, first released in 1986 and later ported to numerous home computers and game consoles. The game, starring the twin Bubble Dragons Bub(Bubblun)(バブルン,Baburun?) and Bob(Bobblun)(ボブルン,Boburun?), is an action-platform game in which players travel through one hundred different stages, busting and pushing bubbles, avoiding enemies and collecting a variety of items. The game became very popular and led to a long series of sequels and spin-offs. The main goal of the game is to rescue Bub and Bob's girlfriends from monsters. It is also notable for being an early example of a game with multiple endings, which depended on the player's skill and discovering secrets.

In the game, each player controls one of the two Bubble Dragons, Bub and Bob. The player can move along platforms, as well as jump to those above and to the side, similar to most platform games. The dragons can blow bubbles. These can trap enemies, who are defeated if the bubble is then burst by the player's spiny back. The bubbles also float for a time before bursting, and can be jumped on, allowing access to otherwise inaccessible areas. Players progress to the next level once all enemies on the current level are defeated. Enemies turn "angry"—becoming pink-colored and moving faster—if they are the last enemy remaining, escape from a bubble after being left too long, or a certain amount of time has been spent on the current level. After a further time limit expires, an additional invincible enemy appears for each player, actively chasing them using only vertical and horizontal movements. Contact with enemies and their projectiles is deadly, resulting in the loss of a life.
